Abstract
The influence of three Bis (indolyl) methanes (BIMs) namely, 3,3?-((4-nitrophenyl) methylene) bis (1H-indole) (BIM-1), 3,3?-(phenyl methylene) bis (1H-indole) (BIM-2) and 4-((1H-indol-2-yl)(1H-indol-3-yl) methyl) phenol (BIM-3) on the mild steel corrosion in 1 M \HCl\ was studied by weight loss, electrochemical, scanning electron microscopy (SEM), and dispersive X-ray spectroscopy (EDX) methods. Results showed that BIM-3 shows maximum inhibition efficiency of 98.06% at 200 mg L?1 concentration. Polarization study revealed that the \BIMs\ act as mixed type inhibitors. Adsorption of \BIMs\ on the mild steel surface obeyed the Langmuir adsorption isotherm. The weight loss and electrochemical results were well supported by \SEM\ and \EDX\ studies.
